Fig. 4: Agent-based models reproduce complex pathway dynamics whilst incorporating spatial information.

ABM simulations (solid lines) of apoptosis execution were compared to equivalent ODE simulations (dashed lines) for pro, activated or complex forms of caspase 9 (a); pro, activated or complex forms of caspase 3 (b); and XIAP or SMAC complexes (c). Visualisations of a single simulation were captured at 0, 7.5, 15 and 30 mins. All simulations were for 30 min, the time step Δt for particle diffusion was 0.0001 s and for reactions was 0.05 s in all simulations. Data in a–c represent results from a single simulation. Data in b represents mean +/− range (thin grey lines) from three independent simulations.
